Ball end mill cutting in gradient optimizing feed.

This paper describes a ball end mill cutting in gradient optimizing feed. The method consists of cutting of optimized feed on each gradient in three dimensional curved surface (thereafter referred to as gradient optimizing feed). An attempt was made to cutting in rising gradient cutting, falling gradient cutting in an inclined plane with ball end mill. It was observed that there was optimized feed in each gradient degree. So, an attempt was made to cutting in gradient optimizing feed and continuous feed. As a result, it was found that the gradient optimizing feed was successful not only in improving tool life, but also in achieving better finished surface roughness.
